So I wanna make a nice survival house/base in minecraft 360 edition. I plan to start a new world soon with my two friends playing split screen and I wanna make a survival house to have separate rooms and stuff for like enchanting and overall storage and maybe a small sheep farm for wool and food farm. But how do I do that? I’ve seen iJevin on YouTube make something like that in a mountain and he has a light blue wool floor and a bunch of rooms and stuff and I want to do that. How do I make it? So here’s a couple questions:
1) how do I make a sheep farm so I can dye sheep and collect different wool colors?
2) how do I make a food farm with everything (sugarcane, wheat, pumpkin etc) and is it better to be automatic or manual? Meaning with pistons or not?
3) how do I set up a nice enchanting room?
4) how do I set up a nice potion room?
Also, I had an idea. I wanted to make a modern kind of house, and then use the basement for all this stuff; enchanting rooms, storage room (a big one) etc and a mining system underneath. Should I do that or just make a survival house and nothing modern ish?
